Abstract：
Under conditions near the center of the Sun, it shows that ⁷Be atoms are completely ionized between R=0 to R=0.1217R _⊙. The newly calculated ⁷Be and ⁸B solar neutrino fluxes are about 4.00×10 ⁹cm ^－2·s ^－1and 6.18×10 ⁶cm ^－2·s ^－1, while the corresponding predicted values of the standard solar model are 4.80×10 ⁹cm ^－2·s ^－1and 5.15×10 ⁶cm ^－2·s ^－1,respectively. It will further increase the discrepancy between the observed and the predicted neutrino fluxes in Super Kamiokande neutrino experiment.
